First Results of an External Quality Assessment (EQA) Scheme for Molecular, Serological and Antigenic Diagnostic Test for SARS-CoV-2 Detection in Lombardy Region (Northern Italy), 2020–2022

Diagnostics, 2022
For diagnosing SARS-CoV-2 infection and for monitoring its spread, the implementation of external quality assessment (EQA) schemes is mandatory to assess and ensure a standard quality according to national and international guidelines.

Interpretation of EQA results and EQA-based trouble shooting [PDF]

Biochemia Medica, 2017
Important objectives of External Quality Assessment (EQA) is to detect analytical errors and make corrective actions. The aim of this paper is to describe knowledge required to interpret EQA results and present a structured approach on how to handle deviating EQA results. The value of EQA and how the EQA result should be interpreted depends on five key

Survival Analysis to Predict How Color Influences the Shelf Life of Strawberry Leather

Foods, 2022
Color change of fruit-based products during storage is an important quality parameter to determine their shelf life. In this study, a combination of relative humidity (RH) and illumination was evaluated on the stability of strawberry leathers.

Demystifying EQA statistics and reports [PDF]

Biochemia Medica, 2017
Reports act as an important feedback tool in External Quality Assessment (EQA). Their main role is to score laboratories for their performance in an EQA round. The most common scores that apply to quantitative data are Q- and Z-scores. To calculate these scores, EQA providers need to have an assigned value and standard deviation for the sample.

Interpreting EQA—Understanding Why Commutability of Materials Matters [PDF]

Clinical Chemistry, 2022
There is a risk to patients of misdiagnosis or incorrect treatment because of bias between results reported from different laboratories/methods for the same measurand. This risk can be identified and hopefully reduced by using External Quality Assurance/Proficiency Testing (EQA/PT) programs when commutable samples are used to identify these differences
